本发明涉及一种在异步通信网络和同步通信网络之间进行多模式多频段切换的方法，更具体地说，本发明涉及一种在异步通信网络和同步通信网络之间进行多模式多频段切换的方法以及相应的移动通信终端。 The present invention relates to a method for multi-mode multi-band switching between asynchronous communication network and synchronous communication network, and more particularly, the present invention relates to a multi-band multi-mode for performing handover between asynchronous communication network and synchronous communication network the method and corresponding mobile communication terminal.

技术背景 technical background

随着移动通信技术的发展和通信网络的改善，开发出了各种类型的移动通信系统，为了解决移动通信系统之间的全球漫游问题， With the development and improvement of communication networks of mobile communication technology, the development of various types of mobile communication systems, in order to solve the problem of global roaming between mobile communication systems,

IMT-2000系统应运而生。 IMT-2000 system came into being.IMT-2000系统分为基于CDMA 2000的同步系统和基于WCDMA的异步系统。 IMT-2000 CDMA system is divided into a synchronous system and asynchronous system based on WCDMA.

此外，为了支持移动通信系统之间的全球漫游，有一种移动通信终端（多模式多频段移动通信终端）既可用在同步系统中，也可用在异歩系统中，使用这种移动通信终端，在同步系统区域和异步系统区域中均可使用各种不同的服务系统。 Further, in order to support global roaming between mobile communication systems, there is a mobile communication terminal (multi-mode multi-band mobile communication terminal) used in a synchronous system can also be used in a heterologous ho system, a mobile communication terminal, in synchronous and asynchronous system area system area can use a variety of service systems.

当前，异步移动通信系统的实现集中在对这种服务有很大需求的区域。 Currently, the asynchronous mobile communication system is concentrated in areas of high demand for such services.因此，同步移动通信系统如下开发：同步移动通信系统的服务区域包括异步系统的服务区域。 Accordingly, the synchronous mobile communication system following development: synchronous mobile communication system comprises a service area of ​​the service area of ​​the asynchronous system.在该过程中，如果用户在异步移动通信系统区域和同步移动通信系统区域之间来回移动，那么，需要在系统之间切换，从而提供连续的服务。 In this process, if the user area and the asynchronous mobile communication system moves back and forth between a synchronous mobile communication system area, then the need to switch between systems, to provide a continuous service.

就此而言，因为异步移动通信系统的通信系统不同于同步移动通信系统的通信系统，所以，很难实现系统间的切换，并且，通过当前的切换方法提高切换的成功率是有限的。 In this regard, because the asynchronous mobile communication system, a communication system is different from the synchronous mobile communication system, a communication system, it is difficult to achieve inter-system handover, and handover success rate is increased by the limited current switching method.另外，由于多模式多频段还包括两个调制解调器，所以，确定这两个调制解调器的开关时间是很重要的。 Further, since the multi-mode multi-band further comprises two modems, thus determining the switching time of the two modems is very important.

域中进行切换，则终端需要大约10秒的时间来触发切换和使同歩调 Switching domain, the terminal takes about 10 seconds to trigger a switch and that the same tune ho

制解调器工作。 Modem work.同步调制解调器工作后，经常不执行切换，这是因为移动通信终端移动到了无线环境的接收信号状态不好的地方。 After the synchronous modem work, often do not perform a handover because the mobile communication terminal moves to a bad signal reception state of the wireless local environment.

此外，在从异步移动通信系统向同步移动通信系统切换时，如果移动通信终端的同步调制解调器早于所需而工作，则异步调制解调器和同步调制解调器同时处于工作状态。 Further, when switching from the asynchronous mobile communication system to the synchronous mobile communication system, if the synchronous modem of the mobile communication terminal operates earlier than desired, the asynchronous modem and the synchronous modem simultaneously in operation.因此，存在着移动通信终端功耗增加这一缺点。 Thus, there is a mobile communication terminal power consumption to increase this drawback.

另外，如果切换成功，则在移动通信终端中需要初始功率计算方法，以便转换到同步移动通信系统中的成功业务传输状态。 Further, if the handover is successful, it requires an initial power calculation method in a mobile communication terminal, the transmission to shift to business success status synchronous mobile communication system.但是，就尝试从异步移动通信系统向同步移动通信系统切换而言，移动通信终端在同步移动通信系统的空闲状态下不经过随机访问，而直接转换到业务传输状态。 However, attempts to handover from the asynchronous mobile communication system to the synchronous mobile communication system, the mobile communication terminal in a synchronous mobile communication system under idle state without going through the random access, converted directly to the service transmission status.因此，向同步移动通信系统切换的移动通信终端经常无法转换到业务传输状态。 Accordingly, the mobile communication terminal switches to the synchronous mobile communication system often can not be converted to a service transmission state.

上面解释了移动通信终端的一个例子，当它进入切换小区区域时，同步调制解调器工作，当从移动通信终端发出呼叫或者从异步移动通信系统接收到呼叫时，同步调制解调器工作。 The above explains an example of the mobile communication terminal when it enters the handover cell area, the synchronous modem operation, when a call is placed or received from the mobile communication terminal from the asynchronous mobile communication system call, the synchronous modem work.下面将给出更详细的说明。 The following description will be given in more detail.

图3的流程图根据本发明第一个实施例示出了在同步通信网络和异步通信网络之间切换的方法。 3 is a flowchart according to a first embodiment of the present invention illustrates a method between a synchronous communication network and the asynchronous communication network handover.例如，当位于异步通信网络中的多模式多频段移动通信终端发出呼叫或者从异步移动通信网络接收到呼叫时，移动通信终端10的同步调制解调器133工作。 For example, when in the asynchronous communication network in a multi-mode multi-band mobile communication terminal sends or receives a call from the asynchronous mobile communication network the call to the mobile communication terminal 10 to the synchronous modem 133 work.

如果位于异步通信系统服务区域中的移动通信终端10发出呼叫或者从同步移动通信系统20收到呼叫时（SIOI)，移动通信终端10 的异步调制解调器123请求同步调制解调器133工作（S103)。 If a call is located in the mobile communication terminal 10 sends an asynchronous communication system service area, or when the synchronous mobile communication system 20 receives a call (SiOI) from the asynchronous modem 123 of the mobile communication terminal 10 requests the synchronous modem 133 work (S103).

ii在同步调制解调器133工作和执行初始化之后，同步调制解调器 After work and ii 133 performs synchronous modem initialization, the synchronous modem

133转换到低功率模式（S107)。 133 transitions to a low-power mode (S107).此时，同步调制解调器133的低功率模式表示：虽然同步调制解调器133通电，但是，信息的发送和接收暂停，并且调制解调器的CPU停止工作。 In this case, the synchronous modem 133 represents a low power mode: While the synchronous modem 133 is energized, however, the suspension information transmission and reception, and modem CPU stops.当前功耗量是in - 1.5口， 其小于现有空闲状态的功耗量。 The current power consumption amount in - 1.5 mouth, which is less than the conventional power consumption idle state.这里，同步调制解调器133需要大约1秒的时间从低功率模式转换到空闲状态。 Here, the synchronous modem 133 requires a time of about 1 second transition from a low power mode to the idle state.

当使用异步移动通信系统20服务的移动通信终端10穿过切换小区区域移到同步移动通信系统30的服务区域时，异步移动通信系统20和异歩调制解调器123执行切换的触发（S109)。 When using the asynchronous mobile communication system 20 serving the mobile communication terminal 10 through the handover cell area to a synchronous mobile communication system 30 of the service area, the asynchronous mobile communication system 20 and executed modem iso ho trigger switch 123 (S109).

异步调制解调器123请求同步调制解调器133转换到空闲状态(Slll)，同时请求切换到异步移动通信系统（S113)。 The asynchronous modem 123 requests the synchronous modem 133 transitions to the idle state (S111), while requesting the handover to the asynchronous mobile communication system (S113).此时，异步调制解调器123发送从异步移动通信系统20的基站收发台获取的系统 At this time, the asynchronous modem transmission system 123 acquired from the base transceiver station of the asynchronous mobile communication system 20

〈曰息。 <Said information.

根据步骤Slll中转换到空闲状态的请求，同步调制解调器133 搜索同步移动通信系统的导频信道和同步信道（S115、 S117)，然后转换到空闲状态（S119)。 According to step Slll request the transition to the idle state, the synchronous modem 133 searches the synchronous mobile communication system, a pilot channel and a synchronization channel (S115, S117), and then transitions to the idle state (S119).

之后，异步移动通信系统20指示异步调制解调器123根据在步骤S113中从异步移动通信系统的基站收发台获取的系统信息，执行切换（S121)，异步调制解调器123通过公共模块140请求同步调制解调器133转换到业务传输状态（S123)。 Thereafter, the asynchronous mobile communication system 20 instructs the asynchronous modem 123 in accordance with the system information in step S113, acquired from the base transceiver station of the asynchronous mobile communication system to perform handover (S121), the asynchronous modem 123 requests through the common module 140 synchronous modem 133 converted to business transmission state (S123).

相应地，同步调制解调器133执行初始化，以便转换到业务传输状态，并发送后向业务，以便与同步移动通信系统30同步（S127)。 Accordingly, the synchronous modem 133 performs the initialization, to shift to a traffic transmission status, and to send the traffic, 30 to synchronize with the synchronous mobile communication system (S127).

然后，同步调制解调器133向同步移动通信系统30的基站收发台报告，切换结束（S129)，接着，通过公共模块140使异步调制解调器123和异步声码器124不工作，并使同步移动通信系统工作，同步声码器134转换声码器。 Then, the synchronous modem 133 to the base station transceiver 30 of the synchronous mobile communication system station reports, handover end (S129), Next, the common module 140 that the asynchronous modem 123 and the asynchronous vocoder 124 does not work, and the synchronous mobile communication system work, vocoder 134 converts the synchronous vocoder.

在从异步移动通信系统20切换到同步移动通信系统30之后，移动通信终端10的同步调制解调器133在切换前维持呼叫连接状态完好。 In the asynchronous mobile communication system 20 is switched to the synchronous mobile communication system 30, after the synchronous modem of the mobile communication terminal 133 before the switch 10 is maintained in good condition call connection.

图4的流程图根据第二个实施例示出了在同步通信网络和异步 The flowchart of FIG 4 according to a second embodiment is shown in asynchronous and synchronous communication network

12通信网络之间切换的方法。 The method of switching between the communication network 12.例如，如果位于异步通信网络中的多模式多频段移动通信终端移动到切换小区区域中，则移动通信终端10的同步调制解调器133工作。 For example, if the asynchronous communication network is located in a multi-mode multi-band mobile communication terminal moves into the handover cell area, the synchronous modem of the mobile communication terminal 10 of the work 133.

如果移动通信终端10从异步移动通信系统进入同步移动通信系 If the mobile communication terminal enters the synchronous mobile communication system 10 from the asynchronous mobile communication system

统的服务区域，则移动通信终端10的异步调制解调器123从同步切换小区区域的基站收发台获取系统信息，并认识到移动通信终端10 进入切换小区区域。 The system service area, the asynchronous modem of the mobile communication terminal 10 of the base transceiver station 123 synchronous handover cell area from the acquired system information, and recognize the mobile communication terminal 10 enters the handover cell area.相应地，异步调制解调器123通过公共模块140 请求同步调制解调器133工作（S203)。 Accordingly, the asynchronous modem 123 synchronous modem 133 work (S203) by the common module 140 requests.

在本发明中，如果移动通信终端10的异步调制解调器123进入切换小区区域，它就自动请求运行同步调制解调器133。 In the present invention, if the asynchronous modem 123 of the mobile communication terminal 10 enters the handover cell area, it automatically requests the synchronous modem 133 to run.

相应地，移动通信终端10的同步调制解调器133工作，从而搜寻调制解调器的初始化过程和同步移动通信系统30的导频信道，并执行初始化（S205)。 Accordingly, the synchronous modem of the mobile communication terminal 133 of the work 10, thereby turning the modem initialization process and a search for the synchronous mobile communication system, the pilot channel 30, and performs initialization (S205).

在同步调制解调器133工作和执行初始化后，同步调制解调器133转换到低功率模式（S207)。 After the work 133 and the synchronous modem initialization is performed, the synchronous modem 133 to convert the low-power mode (S207).此时，同步调制解调器133的低功率模式表示：虽然同步调制解调器133通电，但是，信息的发送和接收暂停，并且调制解调器的CPU停止工作。 In this case, the synchronous modem 133 represents a low power mode: While the synchronous modem 133 is energized, however, the suspension information transmission and reception, and modem CPU stops.当前功耗量是1!D〜1.5口， 其小于现有空闲状态的功耗量。 The current power consumption is 1! D~1.5 port, which is smaller than the conventional power consumption idle state.这里，同步调制解调器133需要大约1秒的时间从低功率模式转换到空闲状态。 Here, the synchronous modem 133 requires a time of about 1 second transition from a low power mode to the idle state.

当使用异步移动通信系统20服务的移动通信终端10穿过切换小区区域移到同步移动通信系统30的服务区域时，异步移动通信系统20和异步调制解调器123执行切换的触发（S209)。 When using the asynchronous mobile communication system 20 serving the mobile communication terminal 10 through the handover cell area to a synchronous mobile communication system 30 of the service area, the asynchronous mobile communication system 20 and the asynchronous modem 123 to perform handover triggering (S209).

异歩调制解调器123通过公共模块140请求同步调制解调器133 转换到空闲状态（S211)，同时请求切换到异步移动通信系统（S211)。 Iso ho modem 123 requests the synchronous modem 140 through the common module 133 transitions to the idle state (S211), while requesting the handover to the asynchronous mobile communication system (S211).此时，异步调制解调器123发送从异步移动通信系统20的基站收发台获取的系统信息。 At this time, the asynchronous modem 123 transmits the system information acquired from a base transceiver station of the asynchronous mobile communication system 20.

根据步骤S211中转换到空闲状态的请求，同步调制解调器133 搜索同歩移动通信系统的导频信道和同步信道（S215、 S217)，然后转换到空闲状态（S219)。 The step S211 of requesting a transition to an idle state, the synchronous modem 133 ho search with a mobile communication system a pilot channel and a synchronization channel (S215, S217), and then transitions to the idle state (S219).

相应地，同步调制解调器133执行初始化，以便转换到业务传输状态，并发送后向业务，以便与同步移动通信系统30同步（S227)。 Accordingly, the synchronous modem 133 performs the initialization, to shift to a traffic transmission status, and to send the traffic, 30 to synchronize with the synchronous mobile communication system (S227).

然后，同步调制解调器133向同步移动通信系统30的基站收发台报告，切换结束（S229)，接着，通过公共模块140使异步调制解调器123和异步声码器124不工作，并使同步移动通信系统工作，同步声码器134转换声码器（S231)。 Then, the synchronous modem 133 to the base station transceiver 30 of the synchronous mobile communication system station reports, handover end (S229), Next, the common module 140 that the asynchronous modem 123 and the asynchronous vocoder 124 does not work, and the synchronous mobile communication system work, synchronous vocoder vocoder converter 134 (S231).

图5的示意图根据本发明第三个实施例给出了处于同步移动通信系统中的移动通信终端的状态变化，示出了从异步移动通信系统向同步移动通信系统切换的移动通信终端转换到业务传输状态的过程。 5 shows a schematic view of a state change of the mobile communication terminal in the synchronous mobile communication system according to a third embodiment of the present invention, showing a converter of the mobile communication terminal from the asynchronous mobile communication system, handover to the synchronous mobile communication system to a service process transmission state.

如图5所示，在从异步移动通信系统20切换到同步移动通信系统30和从同步调制解调器初始化状态转换到空闲状态后，如果位于同步移动通信系统中的多模式多频段移动通信终端10转换到业务传输状态，它就直接转换到业务传输状态，而不经过现有的系统接入状态。 5, the asynchronous mobile communication system 20 is switched to the synchronous mobile communication system 30 and converted from synchronous modem initialization state to the idle state, the multi-band mobile communication terminal is located, if the synchronous mobile communication system 10 transitions from the multi-mode service transmission state, it is converted directly to the service transmission state, without passing through the conventional system access state.

在执行切换之后，直接转换到业务传输状态而不经过现有的系统接入状态的理由在于：在从异步移动通信系统向同步移动通信系统切换时，提前搜索导频信道和同步信道等。 After performing the handover reason, a direct transition to a traffic transmission state without passing through the conventional system access state in that: when switching from the asynchronous mobile communication system to the synchronous mobile communication system, a pilot channel search in advance, and the synchronization channel and the like.下面将对此进行更详细的说明。 This will be described in more detail below.

图6的流程图根据本发明第三个实施例示出了设定同步通信网络中的移动通信终端的初始发射功率的方法。 6 is a flowchart according to a third embodiment of the present invention shows a method of setting the initial transmit power of the mobile communication terminal in the synchronous communication network.例如，在异步移动通信系统服务期间，移动通信终端可以向同步移动通信系统发送信号或者从同步移动通信系统接收信号。 For example, during the asynchronous mobile communication system service, the mobile communication terminal may send a signal to the synchronous mobile communication system or receiving signals from the synchronous mobile communication system.

如果移动通信终端10从异步移动通信系统进入同步移动通信系统的服务区域，则移动通信终端10的异步调制解调器123从同步切换小区区域的基站收发台获取系统信息（S301)，并认识到移动通信终端10进入切换小区区域。 If the mobile communication terminal 10 enters the service area of ​​the synchronous mobile communication system from the asynchronous mobile communication system, the mobile asynchronous modem communication terminal 10 123 synchronous handover from a base transceiver station cell area acquire system information (S301,), and recognizing that the mobile communication terminal 10 enters the handover cell area.相应地，异步调制解调器123通过公共 Accordingly, the asynchronous modem 123 via the public

在本发明中，如果移动通信终端10的同步调制解调器133进入切换小区区域，它就自动请求运行同步调制解调器133，包括系统信息在内的信号与异步移动通信系统使用相同的频率。 In the present invention, the synchronous modem 133 if the mobile communication terminal 10 enters the handover cell area, it automatically request to run a synchronous modem 133, system information including a signal including the asynchronous mobile communication system using the same frequency.

相应地，移动通信终端10的同步调制解调器133工作，并执行初始化，从而搜寻调制解调器的初始化过程和同步移动通信系统的导频信道（S304);搜索同步移动通信系统30的导频信道和同步信道(S305、 S306);并转换到空闲状态（S307)。 Accordingly, the mobile communication terminal synchronous modem 10 133 work, and performs initialization so that the search initialization process the modem and the synchronous mobile communication system, a pilot channel (S304,); Searching for the synchronous mobile communication system, a pilot channel 30 and a synchronization channel ( S305, S306); and transition to the idle state (S307).

之后，异步移动通信系统20指示异步调制解调器123根据在步骤S303中从异步移动通信系统获取的系统信息执行切换（S308)，异步调制解调器123向同步调制解调器133发送信道分配消息（S309)。 Thereafter, the asynchronous mobile communication system 20 instructs the asynchronous modem 123 (S308), the asynchronous modem 123 assignment message to the synchronous modem 133 performs transmission channel based on the information acquired in step S303 to switch the system from the asynchronous mobile communication system (S309).

在歩骤S308和S309中，异步移动通信系统20向异步调制解调器123发送INIT-PWR(异步通信网络的初始功率值，后面称之为"初始功率值")，异步调制解调器123在向同步调制解调器133发送信道分配消息时发送从同步移动通信系统20发送的初始功率值。 Ho in step S308 and S309, the asynchronous mobile communication system 20 transmits 123 INIT-PWR (initial power value of the asynchronous communication network, hereafter referred to as "initial power value") to the asynchronous modem, sending the asynchronous modem 123 to the synchronous modem 133 transmitted from the synchronous mobile communication system 20, an initial value of transmission power when the channel allocation message.

此时，初始功率值（INIT-PWR)表示网络运营商根据特定的小区环境可以不定地使用的值。 In this case, the initial power value (INIT-PWR) represents the value of the network operators can be used variably depending upon the particular cell environment.其大小是从移动通信终端输出的平均功率值，后者不定地取决于小区环境。 Its size is the average value of the output power from the mobile communication terminal, which is variably dependent on the cell environment.

相应地，同步调制解调器133执行初始化，以便转换到业务传输状态（S310)，并发送后向业务，以便与同步移动通信系统30同步(S311)。 Accordingly, the synchronous modem 133 performs the initialization, to shift to a traffic transmission status (S310), and transmits to the service, 30 to synchronize with the synchronous mobile communication system (S311).

然后，同步调制解调器133向同步移动通信系统30的基站收发台报告切换结束（S312)，接着，通过公共模块140使异步调制解调器123和异步声码器124不工作，并使同步移动通信系统工作，同步声码器134转换声码器（S313)。 Then, the synchronous modem 133 to switch a base transceiver station reports the synchronous mobile communication system 30 to the end (S312), Next, the common module 140 that the asynchronous modem 123 and the asynchronous vocoder 124 does not work, and the synchronous mobile communication system working, Synchronization vocoder vocoder converter 134 (S313).

已经从异步移动通信系统切换到同步移动通信系统且转换到空闲状态的移动通信终端10根据用户请求，转换到业务传输状态，从而从另一移动通信终端发送一条SMS (短消息服务)，或者进行寻呼。 It has been switched from the asynchronous mobile communication system to a synchronous mobile communication system and transition to the idle state of the mobile communication terminal 10 according to a user request, the state transitions to traffic transmission, to transmit an SMS (Short Message Service) from another mobile communication terminal, or by paging.

在同步移动通信系统30中，处于空闲状态的移动通信终端10的 The mobile communication terminal 10 in the synchronous mobile communication system 30, in an idle state

15同歩调制解调器133计算初始发射功率，以便发送到业务传输状态(S314)。 15 calculates the initial transmission power with ho modem 133 for transmission to the traffic transmission status (S314).

在步骤S314中，由移动通信终端10的同步调制解调器133设定的初始发射功率值根据[公式I]计算： In step S314, the synchronous modem of the mobile communication terminal 10 is set to 133 in accordance with an initial transmission power value [Formula I] Calculated:

发送并由同步调制解调器接收的平均功率值。 By synchronous modem transmission average power value received.高的接收功率意味着：当前移动通信所属的同步移动通信系统30的环境良好。 High reception power means: this favorable environment synchronous mobile communication system 30 of the mobile communication belongs.因此，在设 Thus, in the set

定移动通信终端的初始发射功率值时，如果同步调制解调器133的平均接收功率值高，则确定初始发射功率值为低，如果同步调制解调器133的平均接收功率值低，则确定初始发射功率值为高。 When given initial transmission power value of the mobile communication terminal, if the synchronous modem of high average received power value 133, determining an initial transmission power value is low, if the synchronous modem 133 average reception power value, it is determined that the initial transmit power value is high .

另外，初始功率值是在步骤S309中从异步移动通信系统发出并由异步调制解调器发向同步调制解调器的值。 Further, the initial power value is a value sent by the asynchronous modem to the synchronous modem sent from the asynchronous mobile communication system at step S309.由于移动通信终端10直接转换到业务传输状态而不经过现有的系统接入状态，从而确定空闲状态下的初始发射功率，所以，反映了在异步移动通信系统中确定的初始功率，从而确定初始发射功率。 Since the mobile communication terminal 10 is directly converted to a traffic transmission state without passing through the conventional system access state, thereby determining the initial transmission power in an idle state, it reflects the initial power is determined in an asynchronous mobile communication system, to determine the initial transmission power.在本发明中，初始功率是在网络中基于特定网络环境中的移动通信系统输出且由异步移动通信系统存储的平均功率值确定的值。 In the present invention, and the initial power output is determined by the average power value stored in the asynchronous mobile communication system based on the specific value of the network in a network environment, the mobile communication system.该小区环境得到了反映。 The residential environment is reflected.

偏移功率是根据移动通信终端的内部特性确定的值，确定用网络进行信号发射和信号接收的程度，用于校正该值，其根据移动通信系统终端10的特性而改变。 Power offset is determined based on the internal characteristics of the mobile communication terminal value, determining the extent of signal transmission and signal reception by the network, for correcting the values ​​which vary depending on the characteristics of the terminal 10 the mobile communication system.

移动通信终端10的同步调制解调器133向同步移动通信系统30发送连接请求信号，以此作为计算出来的初始功率值，请求连接同步移动通信系统（S315)。 133 synchronous modem of the mobile communication terminal 10 to the synchronous mobile communication system 30 transmits a connection request signal, as the calculated initial power value, synchronous mobile communication system requesting the connection (S315).

在步骤S315之后，同歩移动通信系统30收到从移动通信终端10的同步调制解调器133作为初始发射功率发送的连接请求信号， After step S315, the mobile communication system 30 with ho received from the synchronous modem of the mobile communication terminal 10 as the connection 133 of the initial transmission power of the transmission request signal,

16并在S316中发送其响应，同步移动通信系统30和移动通信终端10发送和接收控制消息，用于建立呼叫等。 16 and transmits the response in S316, the synchronous mobile communication system 30 and the mobile communication terminal 10 transmits and receives control messages for establishing a call or the like.

以上的详细说明只介绍了移动通信终端在异步移动通信系统服务期间能够向同步移动通信系统发送信号和从同步移动通信系统接收信号的情况。 The foregoing detailed description describes only the case where the mobile communication terminal capable of transmitting and receiving signals from a synchronous mobile communication system signal to a synchronous mobile communication system during asynchronous mobile communication system service.

但是，适用的移动通信终端也可以仅接收同步移动通信系统的信号同时使用异步移动通信系统的服务。 However, application of the mobile communication terminal can receive only the signal synchronous mobile communication systems for mobile communication system using an asynchronous service.
